Fig. 28-6 shows two long, parallel current-carrying wires. the wires carry equal currents i1 = i2 = 20 a in the directions indicated and are located a distance d = 0.5 m apart. calculate the magnitude and direction of the magnetic field at a point located at an equal distance d from each wire.

In order for the bug to fly through the air a force has to push the bug forward. identify this force. how does the bug produce

Atotal charge of –6.50 µc is uniformly distributed within a sphere that has a radius of 0.150 m. what is the magnitude and direction of the electric field at 0.300 m from the surface of the sphere? a) 2.89 × 105 n/c, radially inward b) 6.49 × 105 n/c, radially outward c) 4.69 × 105 n/c, radially inward d) 9.38 × 105 n/c, radially outward e) 1.30 × 106 n/c, radially inward

If two students are running down the hall toward each other, trying to get to class, and they have the same mass and acceleration, what will happen when they collide? will their forces cancel out or will each one experience a reaction?
